I'm working with the ixp425 based system. The u-boot is also working fine except I noticed that the network calls like eth_rx is

That creates problem with the software that has to work with the
U-boot
because whole system is block and timing and stuff won't work.
I have to admit, that I don't really know what you mean. When U-Boot
is
doing ethernet communication, it is not doing anything else. Or am I missing something here?
Of course, timeout handling should work while doing ethernet traffic.
I ment, like I understand the blocking/non-blocking, that function does not exit before it gets something and for example eth_rx case it does not return before it gets message from network.
How do I setup that timeout if that is possible? I looked the ixp425_recv correctly there isn't any timeout. Only sleep between polls to buffer? Maybe that part could be modified the way that it only waits for some time and then exits telling that buffer len is 0. Don't know what that breaks though.
For reason beyond me I have to use base version 1.1.2, but I can
take
some stuff from newer version if it's required to get the
non-blocking
network commands to work.
Please try to use the current (to-of-git) version of U-Boot. What
error
message do you get?
Like I said, reasons beyond me I have to use base version 1.1.2. It's not about what error message I get or not. I know, it does not make sense for me either.
